DETAILED DESCRIPTION

Various wireless cellular communication systems have been implemented, including a 3rd Generation Partnership Project (3GPP) Universal Mobile Telecommunications System, a 3GPP Long-Term Evolution (LTE) system, and a 3GPP LTE-Advanced (LTE-A) system. Next-generation wireless cellular communication systems that are being developed, such as a fifth generation (5G) wireless system/5G mobile networks system, may improve access to information and sharing of data by various users and applications.

5G systems may provide improved user experiences with faster, better, simpler, richer, and more seamless wireless connectivity for content and services. In general, 5G systems may be based upon LTE-A systems with additional new Radio Access Technologies (RATs). 5G systems may provide unified networks and systems to support various services and applications that may have different and sometimes conflicting performance requirements.

5G systems may support higher-speed user experiences by supporting higher bandwidths. In turn, higher bandwidths may be achieved at least in part by supporting higher carrier frequencies, such as by supporting centimeter-wave (cmWave) or millimeter-wave (mmWave) frequencies. However, mid-band frequencies (e.g., carrier frequencies between 6 gigahertz (GHz) and 30 GHz, or between 50 mm wavelength and 10 mm wavelength) and high-band frequencies (e.g., carrier frequencies of 30 GHz and above) may be subject to severe path loss, which can severely deteriorate signal strength and thereby damage performance of wireless communications employing those frequencies. Beamforming may at least partially compensate for the severe path loss of these cmWave and mmWave frequencies by directing radiation in narrow beam widths toward target users, which may accordingly improve signal quality, improve coverage range, and reduce inter-user interference.

For a 5G Evolved Node-B (eNB) (or Access Point (AP)), Downlink (DL) transmissions may accordingly employ Transmitting (Tx) beamforming. Different Tx beams may be used to send a 5G User Equipment (UE) (or Station (STA)) specific transmissions to different UEs. In 5G systems, for signals that may be broadcast, Tx beam sweeping or aggregated Tx-beam-based transmissions may help ensure sufficient coverage for 5G cells.

Discussed herein are various scenarios for stand-alone 5G eNB deployments using cmWave and mmWave frequencies to send 5G System Information Block (xSIB) transmissions by sweeping across sets of Tx beams. Mechanisms for xSIB transmission with Tx beamforming are discussed. In some embodiments, xSIB transmission via sweeping across Tx beams may be employed in conjunction with Incremental Redundancy, such as through Redundancy Version patterns. For some embodiments, xSIB transmissions may be based upon a Tx beam index.

Scheduling of xSIB transmission is also discussed herein. In some embodiments, for xSIB transmission without resource configuration based upon 5G Physical Downlink Control Channel (xPDCCH) transmissions, resource configuration may be derived from a 5G Primary Synchronization Signal (xPSS) transmission, or a 5G Secondary Synchronization Signal (xSSS) transmission, or a 5G Master Information Block (xMIB) via 5G Physical Broadcast Channel (xPBCH). Also discussed herein are scenarios for derivation of frequency resources and subframe type used for xSIB transmission for xPDCCH-less scenarios.

In the following description, numerous details are discussed to provide a more thorough explanation of embodiments of the present disclosure. It will be apparent to one skilled in the art, however, that embodiments of the present disclosure may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring embodiments of the present disclosure.

Note that in the corresponding drawings of the embodiments, signals are represented with lines. Some lines may be thicker, to indicate a greater number of constituent signal paths, and/or have arrows at one or more ends, to indicate a direction of information flow. Such indications are not intended to be limiting. Rather, the lines are used in connection with one or more exemplary embodiments to facilitate easier understanding of a circuit or a logical unit. Any represented signal, as dictated by design needs or preferences, may actually comprise one or more signals that may travel in either direction and may be implemented with any suitable type of signal scheme.

The term “circuit” or “module” may refer to one or more passive and/or active components that are arranged to cooperate with one another to provide a desired function. The term “signal” may refer to at least one current signal, voltage signal, magnetic signal, or data/clock signal. The meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”

The terms “substantially,” “close,” “approximately,” “near,” and “about” generally refer to being within +/−10% of a target value. Unless otherwise specified the use of the ordinal adjectives “first,” “second,” and “third,” etc., to describe a common object, merely indicate that different instances of like objects are being referred to, and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking, or in any other manner.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in other orientations than those illustrated or otherwise described herein.

The terms “left,” “right,” “front,” “back,” “top,” “bottom,” “over,” “under,” and the like in the description and in the claims, if any, are used for descriptive purposes and not necessarily for describing permanent relative positions.

For purposes of the embodiments, the transistors in various circuits, modules, and logic blocks are Tunneling FETs (TFETs). Some transistors of various embodiments may comprise metal oxide semiconductor (MOS) transistors, which include drain, source, gate, and bulk terminals. The transistors may also include Tri-Gate and FinFET transistors, Gate All Around Cylindrical Transistors, Square Wire, or Rectangular Ribbon Transistors or other devices implementing transistor functionality like carbon nanotubes or spintronic devices.

In addition, the various elements of combinatorial logic and sequential logic discussed in the present disclosure may pertain both to physical structures (such as AND gates, OR gates, or XOR gates), or to synthesized or otherwise optimized collections of devices implementing the logical structures that are Boolean equivalents of the logic under discussion.

In addition, for purposes of the present disclosure, the term “eNB” may refer to a legacy eNB, a next-generation or 5G eNB, an mmWave eNB, an mmWave small cell, an AP, and/or another base station for a wireless communication system. For purposes of the present disclosure, the term “UE” may refer to a UE, a 5G UE, an mmWave UE, an STA, and/or another mobile equipment for a wireless communication system.

Various embodiments of eNBs and/or UEs discussed below may process one or more transmissions of various types. Some processing of a transmission may comprise demodulating, decoding, detecting, parsing, and/or otherwise handling a transmission that has been received. In some embodiments, an eNB or UE processing a transmission may determine or recognize the transmission's type and/or a condition associated with the transmission. For some embodiments, an eNB or UE processing a transmission may act in accordance with the transmission's type, and/or may act conditionally based upon the transmission's type. An eNB or UE processing a transmission may also recognize one or more values or fields of data carried by the transmission. Processing a transmission may comprise moving the transmission through one or more layers of a protocol stack (which may be implemented in, e.g., hardware and/or software-configured elements), such as by moving a transmission that has been received by an eNB or a UE through one or more layers of a protocol stack.

Various embodiments of eNBs and/or UEs discussed below may also generate one or more transmissions of various types. Some generating of a transmission may comprise modulating, encoding, formatting, assembling, and/or otherwise handling a transmission that is to be transmitted. In some embodiments, an eNB or UE generating a transmission may establish the transmission's type and/or a condition associated with the transmission. For some embodiments, an eNB or UE generating a transmission may act in accordance with the transmission's type, and/or may act conditionally based upon the transmission's type. An eNB or UE generating a transmission may also determine one or more values or fields of data carried by the transmission. Generating a transmission may comprise moving the transmission through one or more layers of a protocol stack (which may be implemented in, e.g., hardware and/or software-configured elements), such as by moving a transmission to be sent by an eNB or a UE through one or more layers of a protocol stack.

FIGS. 1-4 illustrate mechanisms for xSIB transmission with Tx beamforming. 5G Physical Downlink Shared Channel (xPDSCH) transmissions may be used to transmit xSIB. Various kinds of xSIBs may carry different types of System Information (SI). A UE may need to decode part of an xSIB, for example an xSIB1 and/or an xSIB2, before transmitting an initial access message. A UE may decode an xSIB1 transmission first and may subsequently decode an xSIB2 transmission according to scheduling information indicated by the xSIB1. Other xSIB transmissions, e.g., xSIB3 through xSIB-N, may be decoded in a manner similar to xSIB2. In some embodiments, the xSIB transmissions described may include xSIB1 transmissions only.

In some embodiments, xSIB may be transmitted periodically through sweeping of Tx beams. An xSIB may also be transmitted in a subframe at a subframe offset or starting subframe. In some embodiments, the period and/or subframe offset for xSIB transmissions may be configured by various elements of the wireless communication network. In some embodiments, the period and/or subframe offset for xSIB transmissions may be configured by xMIB transmissions. In some embodiments, the period and/or subframe offset for xSIB transmissions may be configured by at least one of an xPSS transmission, an xSSS transmission, and/or a Beam Reference Signal (BRS) transmission.

FIG. 1 illustrates a periodic xSIB transmission, in accordance with some embodiments of the disclosure. A scenario 100 may comprise an xSIB transmission 111 for a first Tx beam, an xSIB transmission 121 for a second Tx beam, and so on, through an xSIB transmission 191 for an Nth Tx beam.

In scenario 100, a number N of Tx beams may be used for the xSIB transmissions. xSIBs may be transmitted on different Tx beams at a period 104, which may be K subframes. xSIB may also be transmitted at a subframe offset or starting subframe t.

The numbers N, K, and/or t may be configured in various ways. In some embodiments, the numbers N, K, and/or t may be configured by Radio Resource Control (RRC) from a primary cell (PCell). In some embodiments, the numbers N, K, and/or t may be carried in and/or configured by xMIB. In some embodiments, the numbers N, K, and/or t may be configured by and/or derived from xPSS, xSSS, and/or BRS.

In some embodiments, the number N may be calculated as a function of a number of BRS Resource Block (RB) resources as in equation 1 below:

$\begin{matrix} {N = \left\lceil \frac{N_{BRS} \times N_{sym}^{BRS}}{M} \right\rceil} & (1) \end{matrix}$

Where:

-   -   N_(BRS) may denote a number of BRS RB resources;     -   N_(sym) ^(BRS) may refer to a number of symbols for BRS within         one subframe; and     -   M may indicates a number of Tx beams to be aggregated (which may         be configured by a wireless communications network, xMIB, xPSS,         xSSS, and/or BRS).

In one exemplary embodiment, N_(BRS) for an eNB may be 4, and the eNB may be operable to simultaneously transmit 4 beams (e.g., via 4 antenna panels, one or more of which may comprise an array of small antennas). Accordingly, for any given Orthogonal Frequency Division Multiplex (OFDM) symbol, the eNB may transmit beams in 4 directions at the same time. In the exemplary embodiment, N_(sym) ^(BRS) may be 12, and the eNB's resources may transmit by sweeping across Tx beams oriented in various directions over 12 symbols within a subframe. In the exemplary embodiment, M may be 4, and 4 Tx beams may be aggregated (e.g., for an xSIB transmission). For the exemplary embodiment, the number N of Tx beams used for the xSIB transmissions may accordingly be 12.

In some embodiments, in a “single frequency network” mode of operation, multiple eNBs may transmit an xSIB simultaneously at the same time and frequency resource (e.g., at the same resource element (RE) within an RB), which may advantageously gain the benefits of multi-site diversity. In some cases, N may be 1, and aggregated Tx beams may be applied on one or more xSIB transmissions.

FIG. 2 illustrates a periodic xSIB sequence transmission, in accordance with some embodiments of the disclosure. A scenario 200 may comprise a sequence 210 of a number L of xSIB transmissions for a first Tx beam, a sequence 220 of the number L of xSIB transmissions for a second Tx beam, and so on, through a sequence 290 of the number L of xSIB transmissions for an Nth Tx beam. Sequence 210 may comprise a first xSIB transmission 211 for the first Tx beam, sequence 220 may comprise a first xSIB transmission 221 for the second Tx beam, and sequence 290 may comprise a first xSIB transmission 291 for the Nth Tx beam. Within sequence 210, sequence 220, and/or other sequences of xSIB transmissions through sequence 290, a UE may expect the xSIB transmissions to be transmitted via the same Tx beam.

In scenario 200, a number of Tx beams N may be used for the xSIB transmissions. Within sequence 210, sequence 220, and/or other sequences of xSIB transmissions through sequence 290, the xSIB transmissions may be spaced by a period 202, which may be J subframes. The xSIB transmissions may also be transmitted at a subset offset or starting subframe t.

The numbers N, J, and/or t may be configured in various ways. In some embodiments, the numbers N, J, and/or t may be configured by a PCell (e.g. by RRC). In some embodiments, the numbers N, J, and/or t may be carried in and/or configured by xMIB. In some embodiments, the numbers N, J, and/or t may be configured by and/or derived from xPSS, xSSS, and/or BRS.

In some embodiments, for the L periodic xSIB transmissions within a sequence of xSIB transmissions, Chase Combining or Incremental Redundancy (IR) may be used. For embodiments using IR, different Redundancy Version (RV) patterns may be applied to improve decoding performance. In some embodiments, xSIB transmissions may use an RV pattern that may be predefined as [0 2 3 1], in accordance with, e.g., Release 12 of the 3GPP LTT specification (frozen 2011 Jun. 26). With the same Tx beams applied on the L periodic xSIB transmissions, a UE may perform IR (within a number P of transmissions) to improve detection performance.

In a manner that may be substantially similar to scenario 100, in some embodiments, in a “single frequency network” mode of operation, multiple eNBs may transmit an xSIB simultaneously at the same time and frequency resource (e.g., at the same resource element (RE) within an RB). In some such embodiments, aggregated Tx beams may be applied on each xSIB transmission, and RV pattern [0 2 3 1] may be applied to improve decoding performance.

FIG. 3 illustrates a periodic interleaved consecutive xSIB sequence transmission, in accordance with some embodiments of the disclosure. A scenario 300 may comprise a sequence 310 of xSIB transmissions for a first Tx beam, a sequence 320 of xSIB transmissions for a second Tx beam, and so on, through a sequence 390 of xSIB transmissions for an Nth Tx beam. Sequence 310 may comprise a first xSIB transmission 311 for the first Tx beam, sequence 320 may comprise a first xSIB transmission 321 for the second Tx beam, and sequence 390 may comprise a first xSIB transmission 391 for the Nth Tx beam.

The first xSIB transmissions of sequence 310, sequence 320, and/or other sequences of xSIB transmissions through sequence 390 may be transmitted in N consecutive symbols or subframes. Accordingly, first xSIB transmission 311 (of sequence 310, for the first Tx beam) may be transmitted in a first symbol or subframe, and first xSIB transmission 321 (of sequence 320, for the second Tx beam) may be transmitted in a second symbol or subframe, and so on, consecutively, through first xSIB transmission 391 (of sequence 390, for the Nth Tx beam), which may be transmitted in an Nth symbol or subframe. In addition, a UE may decode repeated xSIB transmissions together.

In scenario 300, a number of Tx beams N may be used for the xSIB transmissions. Within sequence 310, sequence 320, and/or other sequences of xSIB transmissions through sequence 390, the first xSIB transmission and the second xSIB transmission of the sequence may be spaced by a period 302, which may be a number J of subframes, for which J may be larger than N. The xSIB transmissions may also be transmitted at a subset offset or starting subframe t.

The numbers N, J, and/or t may be configured in various ways. In some embodiments, the numbers N, J, and/or t may be configured by a PCell (e.g. by RRC). In some embodiments, the numbers N, J, and/or t may be carried in and/or configured by xMIB. In some embodiments, the numbers N, J, and/or t may be configured by and/or derived from xPSS, xSSS, and/or BRS.

FIG. 4 illustrates a periodic non-interleaved consecutive xSIB sequence transmission, in accordance with some embodiments of the disclosure. A scenario 400 may comprise a sequence 410 of a number L of xSIB transmissions for a first Tx beam, a sequence 420 of the number L of xSIB transmissions for a second Tx beam, and so on, through a sequence of the number of L xSIB transmissions for an Nth Tx beam. Sequence 410 may comprise a first xSIB transmission 411 for the first Tx beam, sequence 420 may comprise a first xSIB transmission 421 for the second Tx beam, and the sequence of xSIB transmissions for the Nth Tx beam may comprise a first xSIB transmission for the Nth Tx beam. In addition, a predetermined or configured RV pattern may be employed to improve decoding performance.

Within sequence 410, sequence 420, and/or other sequences of xSIB transmissions through the sequence for the Nth Tx beam, the L xSIB transmissions of each sequence may be transmitted in L consecutive symbols or subframes. Accordingly, first xSIB transmission 411 of sequence 410 may be transmitted in a first symbol or subframe, and a second xSIB transmission of sequence 410 may be transmitted in a second symbol or subframe, and so on, consecutively, through an Lth xSIB transmission of sequence 410, which may be transmitted in an Lth symbol or subframe.

In scenario 400, a number of Tx beams N may be used for the xSIB transmissions. Within sequence 410, sequence 420, and/or other sequences of xSIB transmissions through the Nth sequence, the first xSIB transmissions of each sequences may be spaced from each other by a period 404, which may be K subframes, and K may be larger than N. The xSIB transmissions may also be transmitted at a subset offset or starting subframe t.

With reference to FIGS. 1-4, in some embodiments, Tx beam information for an xSIB transmission may be derived from a Tx beam applied on an xMIB transmission or a BRS transmission. Based upon that information, a UE may decide which subframe in which to decode an xSIB. A number k (for which k∈[1, N]) may be denoted as an index of an xSIB targeted for decoding, and may be indicated by BRS information as in equation 2 below:

k=ƒ(N _(ID) ^(BRS) ,I _(BRS))  (2)

Where:

-   -   ƒ( ) may be a mapping function (which may be defined by the         network);     -   N_(ID) ^(BRS) may indicate an ID of a BRS sequence in which a         maximum BRS Receiving Power (BRS-RP) may be measured by a UE;         and     -   I_(BRS) may denote an RB group index for the BRS (which may         define a relationship between two or more of an OFDM symbol for         a BRS transmission, an RB group index for the BRS transmission,         and a Tx beam index for xSIB transmission).         An exemplary mapping function ƒ( ) may result in equation 3         below (where N_(sym) ^(BRS) may refer to a number of symbols for         BRS within one subframe, as in equation 1 above):

$\begin{matrix} {k = \left\lceil \frac{{I_{BRS} \times N_{sym}^{BRS}} + \left( {N_{ID}^{BRS}{mod}\; N_{sym}^{BRS}} \right)}{M} \right\rceil} & (3) \end{matrix}$

A UE may derive a periodic subframe which may contain an xSIB transmission for safe decoding based on the above equations and relationships. For example, k may indicate an index of a symbol or subframe in which a UE may expect an xSIB transmission for a particular Tx beam. The UE may accordingly target to decode the expected xSIB transmission at a subframe corresponding to the index k.

FIG. 5 illustrates a self-contained Time Division Duplex (TDD) subframe structure, in accordance with some embodiments of the disclosure. To enable low-latency transmissions, a self-contained TDD subframe structure may be used for a 5G system. A Hybrid Automatic Repeat Request (HARQ) acknowledgement (ACK)/negative-acknowledgement (NACK) feedback may be transmitted in a subframe in which an xPDSCH is scheduled.

In FIG. 5, a subframe 500 may comprise an xPDCCH transmission 510, an xPDSCH transmission 520, a guard time 530, and a 5G Physical Uplink Control Channel (xPUCCH) transmission 540. xPDSCH transmission 520 may be scheduled by xPDCCH transmission 510, and may be transmitted immediately subsequent to xPDCCH transmission 510. A UE may decode xPDSCH transmission 520, after which the UE may provide an ACK or NACK as feedback in xPUCCH transmission 540. In some embodiments, a guard time 530 may be present between xPDSCH transmission 520 and xPUCCH transmission 540 in order to accommodate DL-to-UL and/or UL-to-DL switching times and/or round-trip propagation delays.

With reference to FIGS. 1-5, xSIB transmissions may be scheduled in a variety of ways. In some embodiments, xSIB transmissions may be scheduled via xPDCCH transmissions. A Downlink Control Information (DCI) format with DL assignment may include a Modulation and Coding Scheme (MCS) indicator, an RB assignment indicator, and/or one or more others indicators. The xPDCCH transmission and the subsequent xPDSCH transmission carrying an xSIB may be transmitted by the same Tx beam. In some embodiments, an xPDCCH transmission may be used to transmit the DCI for other, common information, such as paging, RAR, power control commands, and/or some UE-specific DCI. Moreover, in cases in which Tx beam sweeping may be applied for xPDCCH transmissions with common search space, repeated transmissions may be advantageous, but may increase system overhead and thereby reduce spectrum efficiency.

Accordingly, in some embodiments, xPDCCH-less operation for xSIB transmission may reduce system overhead and reserve more beam resources for other messages (e.g., UE specific DCI). For xPDCCH-less operation, information regarding resource allocation and MCS may be made available at a UE (e.g., a Machine-Type Communication (MTC) UE) in order to facilitate proper decoding of common control channels. The configuration of the resource allocation may include various parameters, such as:

-   -   a bitmap of subframes used for xSIB transmission;     -   a starting subframe (e.g., with respect to a System Frame Number         (SFN) 0 of the transmitting cell and/or a period of the xSIB);     -   a frequency location of an xSIB transmission;     -   a configuration of an xSIB transmission (e.g., a number of         repeated subframes, a type (e.g. Chase Combining or Incremental         Redundancy), and/or an RV pattern used for xSIB transmission);     -   a parameter for frequency hopping (e.g., a frequency hopping         enable, or a frequency hopping pattern);     -   a starting ODFM symbol for xSIB transmission;     -   an xPDSCH duration for xSIB transmission;     -   a duration of xPUCCH transmission; and/or     -   a configuration parameter (e.g., an xPUCCH presence indicator         for the subframe in xSIB transmission).

In some embodiments, various resource allocation parameters may be predetermined, e.g., by being defined in a specification. For example, a time instance for xSIB transmission may be fixed by specification (e.g., every subframe number 5 within a 20 millisecond period). For some embodiments, one or more resource allocation parameters and/or an MCS of an xSIB transmission may be configured by higher layers via RRC signaling from a PCell.

In some embodiments, one or more resource allocation parameters and/or an MCS may be carried in an xMIB transmission. For example, a limited set of MCS and frequency locations used for xSIB transmission may be defined by specification. One or more fields of an xMIB transmission may indicate one or more combinations of MCS and frequency locations that may be applied for xSIB transmission.

For some embodiments, one or more resource allocation parameters and/or an MCS of an xSIB transmission may be derived from xPSS, xSSS, and/or BRS. For example, a frequency location used for xSIB transmission may be defined as a function of cell ID, virtual cell ID, BRS group ID, SFN, subframe index, and/or slot index. In another example, a set of possible frequency resources for xSIB transmission may be predefined or configured in an xMIB transmission. Furthermore, an exact frequency resource used for xSIB transmission may be derived from this set of possible frequency resources according to a function of physical cell ID and/or subframe index.

In one example, a frequency resource index I_(freq) may be generically defined in accordance with equation 4 below:

I _(freq)=(c ₀ ·N _(cell) ^(ID) +c ₁ ·n _(SF) +c ₂)mod K _(freq)   (4)

Where:

-   -   c₀, c₁, c₂ may be constants (which may be, e.g., predefined in         the specification, or configured by higher layers via xMIB);     -   N_(cell) ^(ID) may be a physical cell ID;     -   n_(SF) may be a subframe index;     -   mod may be a modulo operation; and     -   K_(freq) may be frequency resources configured in an xMIB (e.g.,         a number of frequency resources).

In some embodiments, one or more of the above-described methods may be combined to indicate resource allocation parameters and/or MCS of an xSIB transmission.

FIG. 6 illustrates a Media Access Control (MAC) Protocol Data Unit (PDU) for Random Access Response (RAR) and xSIB, in accordance with some embodiments of the disclosure. A MAC PDU 600 may comprise a MAC header 610, a first RAR 621, a second RAR 622, additional RARs through an Nth RAR 629, an xSIB 630, and/or an optional padding 640.

For some embodiments, xSIB may be transmitted after a 5G Physical Random Access Channel (xPRACH) transmission and may be associated with RAR.

If the UE 1100 is in an RRC Connected state, where it is still connected to the eNB as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the device may power down for brief intervals of time and thus save power.

If there is no data traffic activity for an extended period of time, then the UE 1100 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The UE 1100 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. Since the device might not receive data in this state, in order to receive data, it should transition back to RRC Connected state.

An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.
